Study of the Production of Antinuclear Antibodies and Anti-Ds DNA Antibodies in Rheumatoid Arthritis Patients Treated with TNF Inhibitors
Background/Purpose: The production of autoantibodies, such as anti-nuclear antibodies (ANA) and anti-ds DNA antibodies (anti-DNA), is commonly observed in patients who have been treated with…Abstract Number: 550 • 2015 ACR/ARHP Annual Meeting
Can Anti-TNF-Induced Autoantibody Conversion be Reversed By Switching to Abatacept Therapy in Patients with RA on Background MTX?
Background/Purpose: Anti-TNF therapy for RA is associated with antinuclear (ANAs) and anti-double-stranded DNA (anti-dsDNA) autoantibodies.1,2 The effect of biologics on autoantibody-positive patients is unknown. We…Abstract Number: 446 • 2014 ACR/ARHP Annual Meeting
Immunoglobulin a Antibodies to Cyclic Citrullinated Protein Predominate in Individuals at-Risk for Future Rheumatoid Arthritis
Background/Purpose Immunoglobulin A (IgA) autoantibodies (Abs) to citrullinated proteins (ACPAs) are present in the preclinical period of RA development, a finding that suggests a mucosal…Abstract Number: 357 • 2014 ACR/ARHP Annual Meeting
Development and Validation of a Diagnostic Bead-Based Multiplex Autoantibody Assay:Screening for Autoantibodies to Detect “Seronegative” Rheumatoid Arthritis
Background/Purpose: Autoantibodies (auto-Ab) against citrullinated peptides (ACPA) and rheumatoid factor (RF) are important biomarkers in the diagnostic process of rheumatoid arthritis (RA). However, RF or…Abstract Number: 2302 • 2013 ACR/ARHP Annual Meeting
Anti-Carbamylated Protein Antibody In Japanese Patients With Rheumatoid Arthritis
Background/Purpose: Serology represents a powerful tool for the identification and sub-classification of patients with rheumatoid arthritis (RA). IgM-rheumatoid factor and anti-cyclic citrullinated peptide (CCP) antibodies…Abstract Number: 909 • 2013 ACR/ARHP Annual Meeting
Diagnostic Autoantibody Signatures Of Rheumatoid Arthritis Patients Identified With a Bead-Based Assay Approach
Background/Purpose: Rheumatoid arthritis (RA) is an autoimmune disease typically characterized by chronic inflammation, accumulation of self-reactive B-cells and production of autoantibodies of which anti–cyclic citrullinated…Abstract Number: 912 • 2013 ACR/ARHP Annual Meeting
B-Cell Responses To De Novo Identified Citrullinated Fibrinogen Peptides Are Associated With PTPN22 Risk Allele
Background/Purpose: Antibodies against citrullinated proteins are common in patients with rheumatoid arthritis (RA) and appear prior to the onset of the disease [1]. Many of…Abstract Number: 869 • 2013 ACR/ARHP Annual Meeting
Anti-Carbamylated Protein Antibodies Are Present Prior To The Diagnosis Of Rheumatoid Arthritis and Predict Future Disease Onset
Background/Purpose: Anti-cyclic citrullinated peptide-2 (CCP2) can be present in serum years before a diagnosis of rheumatoid arthritis (RA), and is highly specific (>95%) for the…Abstract Number: 1194 • 2012 ACR/ARHP Annual Meeting
Prevalence of Anti-Peptidylarginine Deiminase Type 4 Antibodies in Rheumatoid Arthritis and Unaffected First-Degree Relatives in Indigenous North American Populations
Background/Purpose: Antibodies directed against peptidylarginine deiminase type 4 (PAD-4) are present in a subset of patients with rheumatoid arthritis (RA) and are associated with more…Abstract Number: 1771 • 2012 ACR/ARHP Annual Meeting
Anti Carbamylated Protein Antibodies (Anti-CarP) Are Present in Arthralgia Patients and Predict the Development of Rheumatoid Arthritis
Background/Purpose: Recently, we discovered a new autoantibody system in rheumatoid arthritis (RA): anti carbamylated protein antibodies (anti-CarP). These antibodies have additional prognostic value in predicting…
